DUNE is a long-baseline experiment for neutrino oscillation studies. Its near detector complex consists of three main parts. One of them is ND-LAr, the liquid-argon time projection chamber (LAr-TPC). In LAr-TPCs, a light collecting system (LCS) is commonly used as a trigger system. In this work, the ND-LAr LCS is considered. The data from ProtoDUNE Dual Phase and Module 0 LAr-TPC prototypes were used to obtain the parameters of scintillation in liquid argon for Geant4 simulation. The response of the Module 0 LCS in events with cosmic muons was then compared with the response of its Geant4 model in identical simulated events to estimate the photon detection efficiency of the ND-LAr LCS. After that, single-particle and two-particle events with different shifts in time and space between tracks were simulated to determine the time and spatial resolution of the ND-LAr LCS. The results obtained allow us to judge whether the characteristics of the ND-LAr LCS satisfy the experiment requirements
